First off what headphones do you plan on getting?
I use the HD 558's and I personally feel there an awesome set of cans for the money, though I can see why bass heads won't like them.
And you don't need to go though any settings for it to play through the headset though it will play from the speakers at the same time.
Also how are the X41's? I personally gave up on turtle beach after how bad my PX21's broke.
The HD558's were my first audiophile headphones. Got rid of them after a month. Just found them boring and dreary. Lacked the bass I wanted for gaming, and the dark veil just killed my music. Audio Technica just announced the new Air series headphones so if they fix the bass then I'll be picking up the AD900x.
The X41's are terrible. You get a constant hiss because of the wireless, and there's a lot of distortion, especially with explosions. The only reason I still have them is because the dock it comes with allows you to use dolby 7.1 with any headphone, so I use my Beyers when I'm not in a chat.
